Because it loses it's strengths in hot water and gains strength in cold water.
is a hot magnet shorter or weaker than a cold magnet
It doesnt. Heat makes magnets weaker while cold will make them stronger.
It doesn't do anything. It will still work.
chocolate
the magnet that works better is the cold magnet
nope
A cold magnet attracts more than a hot magnet. This helps the flow of electricity which therefore helps the electric field, which therefore helps the magnetic field. They use cold magnets to power the LHC which collides hydrogen atoms. Obviously the cold magnet is very attracting.
Pulse in a cold patient will be weaker and slower than normal.
Put it in the fridge
no. Not nesseicerally
It would last longer in cold weather because heating causes a magnet to lose its magnetism.
NO!!
